When moisture seeps into pavement, it expands when it freezes and contracts when it thaws. This flexing of the pavement, combined with the melted water and the stress of vehicular traffic, causes pavement to deteriorate and potholes to form. The Department of Transportation (CDOT) responds to potholes reported through 311’s Customer Service Requests (CSR) system by mapping open pothole requests each morning and routing crews in geographic clusters so as to fill as many potholes as possible per day. This metric tracks the average number of days CDOT takes to complete pothole repairs per week. Total number of requests fulfilled per week is also available by mousing over columns. The target response time for pothole repairs is within 7 days. For more information about pothole repairs, see CDOT’s pothole Frequently Asked Questions page: http://www.cityofchicago.org/content/dam/city/depts/cdot/PotholeFAQ_winter1011.pdf

The Chicago Building Energy Use Benchmarking Ordinance calls on existing municipal, commercial, and residential buildings larger than 50,000 square feet to track whole-building energy use, report to the City annually, and verify data accuracy every three years. The law, which phases in from 2014-2017, covers less than 1% of Chicago’s buildings, which account for approximately 20% of total energy used by all buildings. For more details, including ordinance text, rules and regulations, and timing, please visit www.CityofChicago.org/EnergyBenchmarking The ordinance authorizes the City to share property-specific information with the public, beginning with the second year in which a building is required to comply. This view shows data for a single year.

This dataset includes recommended positions and salaries for 2017 by title (without names) and salary. The dataset is excerpted from the 2017 Budget Recommendations, which is the line-item budget proposed by the Mayor to the City Council for approval. Disclaimer: the “Total Budgeted Unit” column displays either A) the number of employees AND vacancies associated with a given position, or B) the number of budgeted units (ie. hours/months) for that position. “Position Control” determines whether Total Budgeted Units column will count employees and vacancies or hours/months. If a Position Control is 1, then employees and vacancies are displayed; if a Position Control is 0, then the total number of hours/months recorded is displayed. Owner: Budget and Management. Frequency: Data are updated annually. For more information about the budget process, visit the Budget Documents page: http://j.mp/lPotWf.
